IIV IPROVEMENT IN APPARATUS FOR CARBURETING AIR.

Specification forming part of Letters Patent No. 131,025, datedSeptember 3, 1872.

SPECIFICATION.

Specification describing certain Improvements in Apparatus forOarbureting Air, or Gravity Vapor-Lamp, invented by ALoNzo W. PORTER, ofthe city of New York, county of New York and State of New York.

My invention relates to an improved portable carbureting-lamp, andbelongs to the class of carbureting apparatus known as gravity machines.

It consists, first, in a peculiar construction and arrangement of thecarbureting-vessel so as to receive and contain but a small quantity ofhydrocarbon liquid in the lower part, which is distributed over anextended surface in the upper part by means of fibrous or capillarymaterial; second, in a reservoir andcarbureter arranged in relation toeach other in such a manner that the hydrocarbon will flow freely fromone to the other and attain a common level, the carbureter being soconstructed as to contain but a small portion of the hydrocarbon liquidat any time; third, in the combination of a deflector with saidcarbureter on the inside near the top, which causes the air enteringsaid carbureter to pass to the sides of the same before coming incontact with the carbureting material; fourth, in combination with saidcarbureter of a flange extending around the top of the same and soarranged as to catch the heated air arising from the burner and throw itaround the carbureting-vessel fifth, in combination with the chimney ofthe apparatus of an adjustable deflector, by means of which the heatedair may be turned toward the carbureter; all of which will be more fullyhereinafter explained.

By the peculiar construction of my carbureting-vessel the packing orfibrous material contained therein is kept saturated with hydrocarbonliquid without having a large amount of liquid in said vessel, whichfacilitates the warming of said vessel and prevents the boiling of theliquid in the same or the flooding of the service-pipe, and alsoprevents the formation of an excess of gas and consequent smoking of thelight.

The drawing represents a sectional view of my apparatus.

A represents the carburetingvessel, which is made in the form of aninverted cone or approaching thereto, or in such a manner that the lowerportion will be much less in diameter than the upper part, for thepurpose hereinafter described. B is the reservoir, consisting of a largeshallow vessel, largerat the bottom than the top, placed at one side orto the rear of the carbureter, and communicating therewith by means ofthe tube b. Said reservoir is so constructed and arranged in relation tothe carbureter in such a manner that, when full, the level of thehydrocarbon liquid will be below the upper end of the service-pipe O,which extends upward a short distance into the carbureter. D is anair-inlet, and E a deflector secured directly under it in the upper partof the carbureter, which causes the air to pass to the sides of thecarbureter before coming in contact with the carbureting material. Thecarbureter is filled with fibrous or capillary material, such as hair,wicking, sponge, &c. The service-pipe 0 extends downward from saidcarbureter and outward by a bend, and terminates with an Argandgasburner and chimney. F is a flange around the upper portion of thecarbureter for catching and retaining the heated air. G is an adjustable deflector attached to the chimney,

and so constructed and arranged as to be set at any angle or height todeflect the heat toward the carbureter.

The operation of my apparatus will be read ily understood. Thereservoir, upon being filled, supplies a small amount of hydrocarbonliquid to the carbureter, which can never rise beyond the level of thedotted line which is the level of the liquid in the reservoir when full.A portion of the liquid is absorbed and distributed throughout thefibrous or capillary packing in the upper part of the carbureter whereit is exposed to the air to be carbureted. The vapor and air form amixture heavier than the atmosphere, which descends through the pipe Cto the burner. The vaporization of the hydrocarbon is assisted by theheated air arising from the light, which is thrown by the deflectorunder the flange on the carbureter.

What I claim, and desire to secure by Letters Patent, is-

l. A carbureting-vessel constructed and an ranged so as to contain but asmall quantity of hydrocarbon liquid at one time, which is distributedover an extended surface and exposed to the air to be carbureted bymeans of fibrous material, substantially as described.
